Recording data characteristics of Palm Squirrel one of the unique species in Iran (Sistan-Balouchestan province) were conducted in three cities of Chabahar, Nikshahr and Sarbaz from Feb. 2008 to Feb. 2009. For this reseaon, 6 sampling stations (2 in each city) were selected. For recording bioassay data of Palm Squirrel trapping were used. Forty Palm Squirrel were trapped, 23 male and 7 female with the sex ratio of 1:1.3. There were no significant differences in measured features between males and females. The heaviest Palm Squirrel was recorded as 123.5g. and the lightest was 50g. Moreover; the longest and the shortest animal were 292 and 127cm, respectively. Two features, head-body length and ear size showed significant difference among animals caught from three cities. Regression analysis among features showed correlation between head-body length and leg length. On the other hand, ear size and leg length had significant correlation.

Growth performance of rainbow trout studied by use of bread and macaroni industries wastes in Grower diet (as carbohydrate source) replacement of wheat and corn. Seven experimental diets were prepared. Amount of carbohydrate materials replacement in diets were: 1) 100% bread wastes 2) 50% bread wastes 3) 100% macaroni wastes 4) 50% macaroni wastes 5) 100% equal mix of bread and macaroni wastes and 6) 50% equal mix of bread and macaroni wastes. Blank diet prepared as same as commercial common diet. 21 polyethylene net cages (1×1×1m) used for fish holding in a cement pond (30×3×1.2m) with 10l/s water flow. Each cage stoked by 20 fish with initial average weight of 85±5g. Farming period was 75 days and in this period water temperature, pH and dissolved oxygen were 14.5±2°C, 7.5-8.8 and 6.8-8.5mg/l, respectively. The best growth performance belonged to diet 4, although results diets of 2, 4, 6, and blank had no significant differences (P>0.05). In term of economic value of used diets, diets 2 had the best result. Carcass analysis in the end of experiment showed that carcass protein and ash contents in all of treatment were same but lipid content in treatments of 1, 3, and 5 were lower than other treatments (P<0.05).

Some of biological parameters of blood and seminal plasma are different in some of material and there is correlation between some of them. known of biochemical parameters in blood and seminal plasma are necessary for determination of physiologic situation of fish and such known of effective parameters on seminal plasma compositions that have effect on physiologic situation of sperm are necessary. The aim of this investigation was to determinate and compare some of seminal and blood plasma biochemical parameters in Cyprinus carpio. For this purpose 15 wild sea carp fish with weight average (808.88) grams were caught from Gorganrood estuary on May and levels of Ca+2 and Mg+2 ions, total protein, glucose and cholesterol of their blood and seminal plasma were determined. Results show that level of Ca+2 ion significantly was more than seminal (P<0.01) but there are no significant differences between blood plasma and seminal in Mg+2 and total protein (P>0.05). Blood glucose and cholesterol level significantly were more than seminal (P<0.01). There was a significant correlation between Mg+2 and glucose in blood and seminal plasma but there were not significant correlations between other parameters in blood and seminal plasma.

We studied the effect of different salinities on growth, lifespan and maturation time in the Artemia urmiana under laboratory condition. The experiments were done on the control group and 12 treatment groups. Experimental salinities ranged from 30 to 125gL-1. In growth experiments the mean body length of 10 individual Artemia from each treatment were measured in days 1, 5, 11 and 17 and results showed that in high salinities treatments (75,100 & 125ppt) compared at 30ppt were significantly different decrease in growth in A. urmiana (P<0.05). The present study confirms that maximum growth was observed at 30ppt (5.062±0.937mm) minimum growth in A. urmiana was observed at 75ppt (3.156±0.386mm). In lifespan experiments showed that, increasing the amount of salinity in cases lifespan was decreased and maturation time was late. Longest lifespan was observed at 75ppt (67.66±2.516 day) and shortest maturation time for A. urmiana after (27.66±1.527 day) was seen at 75ppt.

In this research, high level of TSS as one of the most problems in RAS (Recirculation Aquaculture System) of Rainbow trout's culture is investigated. Other physical factors of water such as CO2, O2, EC and pH were measured as well. For this reason, 5 typical farms were selected and they were similar in design and construction, production method and consumed meal. In commercial farms, other those remaining Suspended Solids methods, use from chemical method, but this method is not applicable in these sites. Research carried out in period of 6 months and 3 stages (in cycle of two month). Efficiency of removing lipid from system was recognized be investigation of lipid amount of suspended solids. One way ANOVA that carried out between five sites in difference periods, showed that the significant differences (P<0.05). Finally, the results indicated that chemical removing method (with these conditions) is not performed in RAS of Rainbow trout.

The kidney as an excretory organ plays an important role in osmoregulation, fluid and ion balance and solution materials density. We studied the effect of salinity on the trend of changes kidney of Cyprinus carpio in response to different salinities. Eighty Common carp, Cyprinus carpio ranging approximately 986±36g and 24.25±0.17cm of length were collected from the Shahid Malaki fish farm in Ahwaz. The fish were maintained under laboratory conditions for adaptation for one month and were exposed to different salinities such as 3, 6, 9 and 12ppt with a 3-ppt daily increase. When they reached the final desired salinity, they were maintained for 14 additional days. Some fish were kept in FW as a control. No mortality was observed when experimental fish were transferred from freshwater to brackish water. At the end of the period, 5 fish were collected per salinity and sections were stained with hematoxylin and eosin. Microscopic results indicated that there was no significant difference between number of glomeruls in different salinity (P>0.05) as well as between diameter of glomeruls in different salinity (P>0.05). Hence, our data indicates that in culture conditions, adult common carp can survive successfully in brackish water with salinity of up to 9ppt

We Studied feeding regime of Javelin grunt (Pomadasys kaakan) from the coastal waters of Persian Gulf (Hormuzgan province) from November 2005 to September 2006. A total of 227 specimens were collected seasonally (twice per each season). For this aim, different feeding factors such as Food preference, Contents Void Index, Stomach fullness index, Relative Length Gut were measured. Stomach or Contents Void Index (CV or VI) was obtained at 63.4% and showed that Javelin grunt is relatively low feeder (frugal). Furthermore, results of stomach void index specified that Javelin grunt has median feeding in summer and winter seasons, meanwhile in spring and autumn has relatively frugal. Relative Length Gut (RLG) of this species was calculated 0.7 and shows that Javelin grunt is carnivorous fish. Different kinds of food contents were identified in gut consist of: swimmer crab, scorpion crab, bony fishes, asteroids, bivalves, gastropods, cephalopods, shrimps and sea weeds. Food preference was obtained regulatory for crustacean (77.7), fishes (32.1), Mollusks (28.6) and Echinoderms (18.8). Swimmer crab in crustaceans group with FP more than 50% was identified as main food and scorpion crab with FP about 25% was as secondary food. Crab (50.9) in crustacean group, goatfish (family Mullidae) in bony fishes group, Asteroid in echinoderms group and Bivalve in mollusks group had the most food preference in each food group. This records indicated that crab and asteroid in autumn and spring, crab and boney fishes in winter and scorpion crab in summer had the most food preference in each season.
